Welcome to Seasonic

Sea Sonic Electronics Co., Ltd was founded in 1975 by engineers. Since the very early beginnings the company has rigorously maintained its focus on the research, development and production of technologically advanced high quality products. In 1981 Sea Sonic expanded into the production of PC power supplies and became one of the first manufacturers on this market.

As power supply manufacturing became the core identity of Sea Sonic and as a result of continuous advancement in technology, the establishment of the Seasonic brand name has not stayed far behind. Today the Seasonic power supply is the equivalent of high performance, excellence and reliability.

We, at Sea Sonic, strive to develop long term, reliable relationships with our business partners who value our products and share our goals and philosophy. It is our mission to develop long term, mutually beneficial partnerships and to provide timely and professional solutions to meet the IT industry’s ever growing requirements.
